Open Public
Donated compute for open source.
Donors fund open source projects. Maintainers create OpenRouter API keys for top models to help them ship, with token spend open to the public.

Supported tools
Works where maintainers already use model APIs and coding agents.
Compute keys are OpenRouter API keys for leading models, backed by the project's donated compute. The opub CLI adds linked sessions when maintainers want donor-visible project context.
01 / Funding
Donors fund open source projects
Donations grant project maintainers access to over 30 top coding models. They apply it to issues, reviews, bugs, features; whatever helps them ship.
02 / Keys
Maintainers create API keys for top models
Maintainers create OpenRouter API keys from the project balance, then use them with coding agents, model APIs, or custom workflows.
03 / Ledger
Compute spend is public
Public ledgers link agentic sessions to opub for transparency. You can trust your donation went to the project. Spend links back where it belongs.
